This little aspiring astronaut made for the cutest pic taken Tuesday during the Discovery space shuttle's final flight -- and despite the end of the shuttle program, he could still have a future in space.

The space shuttle Discovery flew its final mission today, piggybacking on a Boeing 747 from Kennedy Space Center to D.C., where the shuttle will take up permanent residence as part of the Smithsonian's National Air and Space Museum. To commemorate the end of the shuttle era, NASA launched an extensive Flickr feed for citizen journalists in the flight path, and a roundup of landing pics can be found here. And if that's not enough Discovery for you, there's video here and here, and also a Twitter feed. Phew.
